The objective is to present a practical method of implementing a beamforming module with a general-purpose digital signal processor. The proposed module provides a beam-pattern that has its maximum gain along the direction of a target mobile subscriber using real-time processing. The new technique utilizes a modified CGM (conjugate gradient method) in such… (More)

To effectively evaluate and analyze R&D performance, it is necessary to measure the relative importance of performance analysis factors and quantitative analysis methods that consider the objectivity and relevance of detail factors that constitute performance evaluation. This study suggests a framework for R&D performance evaluations by computing weights… (More)
